“…To verify if the selected landraces could also provide a good nutritional value when grown under high temperatures, the main tomato phytonutrients contents, such as AsA, polyphenols, and carotenoids, were determined. These compounds have been associated to health benefits and the reduction of inflammatory and aging‐related diseases . Therefore, the dietary intake of these compounds is highly recommended.…”

BACKGROUND Global warming and extreme or adverse events induced by climatic fluctuations are an important threat for plants growth and agricultural production. Adaptability to environmental changes prevalently derives from a large set of genetic traits affecting physiological and agronomic parameters. Therefore, the identification of genotypes that are good yield performer at high temperatures is becoming increasingly necessary for future breeding programs. Here, we analyzed the performances of different tomato landraces grown under elevated temperatures in terms of yield and nutritional quality of the fruit. Finally, we evaluated the antioxidant and anti‐inflammatory activities of fruit extracts from the tomato landraces selected. RESULTS The tomato landraces analyzed here in a hot climate differed in terms of yield performance, physicochemical parameters of fruit (pH, titratable acidity, degrees Brix, firmness), bioactive compounds (ascorbic acid, carotenoids, and polyphenols), and anti‐inflammatory potential. Three of these landraces (named E30, E94, and PDVIT) showed higher fruit quality and nutritional value. An estimated evaluation index allowed identification of PDVIT as the best performer in terms of yield and fruit quality under high temperatures. CONCLUSION The analyses performed here highlight the possibility to identify new landraces that can combine good yield performances and fruit nutritional quality at high temperatures, information that is useful for future breeding programs. © 2020 The Authors.

“…Flavonoids are polyphenolic compounds synthesized in plants as bioactive secondary metabolites [1] responsible for their color, flavor and pharmacological activities [2]. The main flavonoid sources are fruits and vegetables [3], and they are also abundant in cocoa products (cocoa powder, chocolate) [4], black and green tea [3,5] and red wine [3,6].…”

Flavonoids as Anticancer Agents

et al. 2020

Flavonoids are polyphenolic compounds subdivided into 6 groups: isoflavonoids, flavanones, flavanols, flavonols, flavones and anthocyanidins found in a variety of plants. Fruits, vegetables, plant-derived beverages such as green tea, wine and cocoa-based products are the main dietary sources of flavonoids. Flavonoids have been shown to possess a wide variety of anticancer effects: they modulate reactive oxygen species (ROS)-scavenging enzyme activities, participate in arresting the cell cycle, induce apoptosis, autophagy, and suppress cancer cell proliferation and invasiveness. Flavonoids have dual action regarding ROS homeostasis—they act as antioxidants under normal conditions and are potent pro-oxidants in cancer cells triggering the apoptotic pathways and downregulating pro-inflammatory signaling pathways. This article reviews the biochemical properties and bioavailability of flavonoids, their anticancer activity and its mechanisms of action.

“…Except for defense, phenylpropanoids in O. dubium flowers may also serve as floral pigments to mediate processes like plant-pollinator interactions. Flavonoids are a large group of phenylpropanoids that provide the plant vivid colors, together with chlorophylls and carotenoids [22]. It includes many compounds like chalcones, isoflavones, flavonols, flavones, dihydroflavonols, anthocyanins and others.…”

“…It includes many compounds like chalcones, isoflavones, flavonols, flavones, dihydroflavonols, anthocyanins and others. Their mixture and blends usually impart the plant with pink to red or blue to purple hues [22]. As shown in Figure 3c, more than half of the flavonoid-related transcript expression of chalcone (chalcone isomerase, etc.…”

Ornithogalum dubium is a popular ornamental monocot native to South Africa with flower colors ranging from pure white to deep orange. Gene editing based on the CRISPR/Cas9 system has recently been shown to hold potential for color improvement in ornamental flower crops. To apply this approach to Ornithogalum color manipulation, genomic or transcriptomic data must first be collected. Here, cDNA libraries of O. dubium leaves and flowers were constructed and sequenced using the Illumina HiSeq 2500. Over 155 million 100-bp paired-end reads were assembled into a transcriptome database of 360,689 contigs, of which 18,660 contigs were differentially expressed between leaves and flowers. Carotenoids are the main pigment imparting spectrum of orange hues to O. dubium flowers. By querying our database, we identified a total of 16 unique transcripts (unigenes) predicted to be involved in the carotenoid biosynthesis pathway of Ornithogalum. Combining carotenoid profiles, we further inferred several key unigenes responsible for floral coloration and accumulation in O. dubium, of which the gene LCYB/comp146645_c0 was found as a suitable target to generate potentially red flower varieties of O. dubium. Our research thus provides a framework for the application of CRISPR/Cas9 technology to improve this ornamental crop.
